Sharefolders on network folders is inacc

I created couple sharefolders on one of the users on the LAN but no one can access these folders. The access type is Read-only. I tried both full access and depend upon password and also both file and print sharing boxes are checked from the controlpanel in the network, but still inaccessable. Any idea what causes this and how to solve this problem?
Thanks
